I will double down on Grayhawk's huge
capital investment. Rigging my IV-P ailerons so the inboard trailing
edges are slightly above the flap trailing edge, in level flight, lightened
my roll stick forces, and reduced hunting from the TT Sorcerer. It now
does not hunt in AP mode.
It still does hunt in GPSS mode.
More so when toggled to the Chelton, less so when toggled to the GNS 430.
I suspect it may have something to do with the Chelton user programmable
settings, but I don't know which ones.
I will also be sending my roll servo to
TT for the high torque and slip clutch upgrade. The low torque does ok at
the Medium bank angle setting but will not handle the High bank angle
setting. I have also sheared the shear screw so the slip clutch seems to
make sense to me.

This is just a suggestion - My $0.00 worth.
Properly rigged ailerons have a slight float or dead band partially
available from lash in the linkage. If so, the airplane may experience
slight lateral imbalance that a sensitive AP may pick up and try to
correct. Holding the stick reduces the dead band movement. So ....
One might try an experiment - Rig the ailerons ever so slightly up (say a
half or full turn in on the final aileron linkage rod end on each
side). This may result in a very slight air load on each aileron in
level flight thus elimination of oscillation in the dead band? This
also results in the up aileron going up more before the down aileron is,
uh, going down.
Like I said, for what it's worth,
Grayhawk

anyone who has a sorcerer find it tracks smooth? On my AFPilot the standard
servo has a problem rolling at high speed. You can hear the servo ratchet as
the stepper motor jumps. Once it does this it starts a sort of
oscillation. Back and forth at a fairly high rate. Doesn't turn to
much. If I hold the stick steady it calms down. From what I see quite a few
have had to upgrade to the higher torque servo. Since I just bought my setup
this year would be nice had they just quoted it with the high torque knowing
the standard might be too weak.
There was an S-TEC 55x in it before. But
since the HSI was upgraded to glass nothing wanted to talk to it anymore.
Barely a fancy wing leveler at that point.
Bill which tru track do
you have? What is it hooked to that is driving it.

Haven't been all that impressed with TT so far.

AFS Pilot? Which servos do you have installed? I. Thinking I need the higher
torque servos on the ailerons at high speed cruise?what settings do you have
it at? I'm trying to dial mine in and get rid of the hunting.
